TDA8444AT/N4,112

Digital To Analog Converters Overview

The TDA8444AT/N4,112 is an octuple 6-bit digital-to-analog converter (DAC) featuring an I²C-bus interface. It operates with a supply voltage range of 4.5 V to 13.2 V and includes three programmable slave address bits for multi-device bus configurations. The device provides eight push-pull outputs with short-circuit protection and adjustable common output swing via the VMAX input. It utilizes a bipolar IC process in an SO20 plastic small outline package.

Digital To Analog Converters Feature Summary

• Eight independent 6-bit DAC channels with push-pull outputs
• I²C-bus slave receiver with programmable addressing
• Adjustable maximum output voltage control
• Short-circuit protection on all analog outputs

Digital To Analog Converters Applications

• Color decoder interface circuits
• YUV/RGB switch control systems
• CRT receiver interface applications

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product specification to confirm package type and tape-and-reel availability. Ensure the component meets the required industrial temperature range specifications before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when multiple low-resolution analog outputs are required within a single I²C address space. The SO20 package offers additional address pins compared to the SO16 variant, allowing for greater flexibility in bus topology design without external logic.

Digital To Analog Converters Part Context

This part belongs to the TDA8444 family of octuple DACs manufactured by NXP Semiconductors. It serves as a specialized interface solution for video processing architectures, specifically designed to manage signal routing and decoding functions through serial communication protocols.

Digital To Analog Converters Replacement Considerations

Direct replacements include the TDA8444T (SO16 package) and TDA8444 (DIP16 package). Verify pin compatibility regarding the A2 address bit availability, as the SO16 variant lacks this specific pin configuration.
